Swine Influenza (swine flu) could be a respiratory disease of pigs caused by type A influenza virus that often causes outbreaks of influenza in pigs. Swine flu viruses can cause high levels of illness in pig herds, but cause few deaths in pigs. Swine influenza viruses can flow into among swine throughout the year, but most outbreaks occur during the late fall and winter months like outbreaks of seasonal influenza in humans. The main swine flu viruses circulating in U.S. pigs lately are: swine triple reassortant (tr) H1N1, trH3N2 and trH1N2. With the exception of the 2009 H1N1 virus, influenza viruses that circulate in swine are terribly totally different from influenza viruses that commonly flow into in people.
